You see that they are "levitate" in the PCB board. I dont know > why they added it. I have a tool to shift the coordinates in a VRML2 file; it was necessary because some models have a large offset. I can't remember if the tool is in my VRML models project though, but I can check. The tool also strips all Transforms and applies them so that the output file has no more transforms; this was to keep KiCad happy since KiCad didn't support non-unity Transforms. I suspect one day I might create a Write() for the model parsers so that I can improve the VRML export. In such a case I would also eliminate the Transforms; for me there is no point in maintaining transforms unless we support the reuse of coordinate lists and vertex indices. At the moment the presence of transforms only increases processing time of the VRML file. - Cirilo _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
